Hi Diane,
Yes, this is with 2013. It's such a crime that Microsoft keeps "updating" without ensuring their product is stable.
Another gripe: Color-coded appointments in their calendar. Why is this not the default? Shameful.

By color-coded, you mean categorized? This is in a calendar in the Calendar (This computer only) folder?

It's a limitation of IMAP accounts - categories don't sync to the server so Microsoft removed the capability from imap accounts to avoid confusion when the categories weren't available on other computers or were removed if a folder resynced. There are ways around it using vba.
